Application inea February 25, 1927; seriai No. 170,975.

This invention relates to improvements in book markers.

rlhe primary object of the invention re-v sides in a book marker adapted to be mounted upon the covers of a book and which" will"automatically mark the pages last eX- posed upon the closing of the book.

Another object of the invention is the provision of a book marking device which may be removably attached to books of different sizes, so that the same may be removed from one book after being read and "applied lto another book. y

A further object is to provide an automatic book marker which is simple in construction, inexpensive of manufacture and` easy to a-pplv or remove from the covers of a book.

' lVith these and other objects in view, the

invention resides in certain novel construction and combination and arrangemet of parts, the essential features of which are hereinafter fully described, are particularly l pointed out inthe appended claims, and are j the front and back covers 11.

illustrated in the accompanying drawing, 1n which s Figure 1 is a perspective view of my 1mproved book marker in position upon a book and showing the book in an open position.

Figure 2 is a similar view but showingy the book in a closed position.

Figure 3 is a vertical sectional v iew "on the line 3-3 of Figure 2. j

Figure 4 is a vertical sectional View on the line 4-4 of Figure 1.

Figure 5 is a similar view on the line 5-5 of Figure l.

Referring more particularly to the drawing, the reference numeral 10 designates a book having rigid front and back covers 11, 11, and bound pages 12 interposed therebetween. y improved book marker is shown in its entirety as at 13 and includes a pair of spring U-shaped clips 14 and 15 which are respectively lattached to the-top edge of The clips have inwardly extending ears 16 stamped and bent therefrom and to which one end of levers 17 and 18 are respectively pivoted. The ear 16 of the clip 15 is slotted as at 19 to receive the pivot of the lever 18 to permit f of a limited sliding movement of the same arms are (zo-extensive vwith the levers 17 and 18, respectively. The levers 17 and 18 are constructed .of a vsingle piece of flat metal` bent upon itselfto provide a v'double ply of material, and it is betweenthesey plies that the arms 2 1 and 22 are pivoted so as vto permit a limited turningmoveinent of the arms'in one direction, as the same abut the closed side of the levers as shown in Figure' reduced portions of T-shaped lugs 24 extending angularly. from a pair of plates 2 5 hingedly connected together as at 26. `In order to arrange the T-shaped lugs in the openings 23,the cross heads of the lugs are folded upon the body portions thereof and after being' passed through the .openings are unfolded to their normal position as shown.` The cross heads of the T-shaped lugs pre-` vent the lugs from being removed from the openings 23 andv provide ay loose or flexible joint between the hinged plates and the free ends of the arms 21 and 22.` s s j In practice, the marking device is attached to the book `in the manner shown in the drawing,'i. e., by passing the lclips 14 andy 15 over the top edges of the covers 11 where they'are held bv reason of their springy nature. As the book is opened as shown in Figure 1. thev arms `21 and 22 are spread apart :which holds theplates 25 'out of the path of the pages- 12 of the book 'to of the free turning of thek pages. hould ermit the book be closed between any two pages closed from an open position on one side of its center of thickness.

From the foregoing description, it will be seen that I have provided a book marking device which is automatic in its action and which may be removed from one book and applied to another when desired.

lVliile 'I have described what I deem to be the most desirable embodiment of my in swingingly mounted covers, of a book mark.-`

ing device including attaching clips for supporting the same upon said covers,a pair of pivoted levers respectively pivoted to said clips and a foldablemember carried by the free ends of said vlevers and foldable between the pages of said book vupon lmovement of the covers from an kopenvto a closed position.

'2; In combination with a book having swingingly mounted covers and pages therebetweemot-a book marking device, including a pair of clips' for attachment to said covers, a member foldablel between said pages, and automatic means attached to said clips for unfolding said member out of the path of said pages upon the opening of said book and for folding said member between two adjacent pages upon the vclosing of said book. i

3. A book marking device comprising attaching clips adapted to be applied to the covers ot a rb`ook,'a oldable member adapted to be moved to a position between two adjacent pages of a book and out of the path of the pages, and automatic means operable upon movement .of said attaching clips to-v ward each other for actuating said foldable member. v

1. A book marking device comprising a` .front and back covers of a book, a pair of levers pivoted to the respective clips and having their free ends pivoted together, arms pivoted to said levers and co--eXtensive therewith, and a foldable member carried by the free ends of said arms substantially as and for the purpose specied.

Tsaid arms substantially as vand for the 'purpose specified. l

6. In a device of the vclass described, the combination of a book having swingingly mounted covers and pages located'between the same, a marker, and connections between said marker and the covers adapted to cause the marker to be inserted between t-he pages upon movement of the covers toward one another in closing movement of the book, and to withdraw said marker from between the pages when the covers are spread apart to open the book.

7. In combination with a book having swingingly mounted covers and pages therebetween, ot' a book marking device,`includr ing` means for attachment to said covers, ay

member movable between said pages, said member being connected te the means for` taclnnent to the covers and automatic means for moving said member out of the path of said pages upon theopening oi'i-the'book and for moving said member between two adjacent pages upon the closing of said book.

In testimony whereof I have aiiiXed my signature.
